TOBACCO-DRIER.

SPECIFICATION forming part of Letters Patent No. 281,168, dated July 10,1883. Appleman filed .ipx-neo, 1an. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT W. VALKER, of Clemmonsville, in the county ofDavidson and State of North Carolina, have invented a new and usefulImprovement in Tobacco- Driers, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,makinga part of this specification, in which- Figure 1 is a perspectiveview of a tobaccodrier with my improvements attached. Fig. 2 is a topView of the same. Fig. 3 is a longi tudinal section through .c w of Fig.2.

My invention relates to devices for drying and curing tobacco in thebarn or tobaccohouse; and it consists in the combination of deviceshereinafter explained and claimed.

To enable others skilled in the art to make and use my invention, I willproceed to describe the exact manner in which I have carried it out.

In the drawings, A represents the fire-box, and B the hot-air chamber,both properly constructed of suitable masonry in the ordinary way, andprovided with cold-airpassages c c c. Over the firebox is the flue D,for the admission of atmospheric air to the hot-air chamber. In practicethe lire-box is constructed on the outside of the building, and thehot-air chamber extends entirely across the inside of the building.Vithin the hot-air chamber, and extending from the iire-box to thechimney on the opposite side of the building, is the pipe E, forcarrying the smoke from the lire to the chimney. This pipe alsomaterially aids in heating up the air, and is to that extent aneconomical construction, as it lessens the amount of fuel necessary fordrying and curing the tobacco. The hot-air chamber is providedwith ametallic cover, F, divided longitudinally in the center, leaving aslight openingy between the two halves, and each side may be looselypivoted at f, near its outside longitudinal center. By this constructionthe ends of each half of the cover can be moved from or toward eachother, so that the ends near the rebox may be brought in contact, ifrequired, so as to diminish the amount of ascending heat at that point,and at the same time the opening is gradually increased toward theopposite end of the chamber, where the heat becomes gradually lessintense, thus securing a means for regularly adj usting the heatentirely across the houses.

Having thus explained my invention, what I claimas new, and desire tosecure by Letters Patent, is-

. 1. In a drying and curing apparatus, the hot-air chamber B, providedwith the metallic cover F, divided longitudinally and having each halfofthe cover adjustable, substantially as and for the purpose described.

2. In a drying andvcuring apparatus, the.

hot-air chamber B, provided with a longitudinally-divided cover, incombination with the fire-box A, flue D, and pipe E, all constructed tooperate substantially as and for the purpose set forth.
